Definitions
- the invention relates to fluid jet cutting machines having cutting heads for producing a high velocity fluid jet for cutting a workpiece. More particularly the invention relates to a cutting head for producing a water jet which contains abrasive materials.
- Fluid jet cutting machines have pumps known as intensifiers that increase the pressure of water in the range of 60,000 psi.
- the ultra high pressure water is forced through a jewel nozzle having a small orifice to generate a jet having a high velocity stream of water.
- abrasive materials have been added to the jet stream.
- the abrasive materials are added to the water downstream from the orifice of the jewel nozzle into a mixing region wherein the abrasive material is entrained with the water jet.
- the abrasive jet After passing through the mixing region, the abrasive jet exits from the mixing region through an elongated outlet nozzle which directs the jet toward the workpiece. It is known that to maximize the life of the mixing nozzle the internal fluid path should be generally concentric with the abrasive jet. The mixing nozzle wears out quickly and becomes inefficient as the material quickly erodes. Concentricity and alignment is difficult to attain. Imperfections in the jewel cause the path of the water jet to deviate. Installation of the jewel can cause further deviation of the water jet from the longitudinal axis of the mixing chamber and nozzle passage. Also, manufacturing tolerences in the parts of the cutting heads can create variations in the water jet path and the longitudinal axis of the path of the orifice, mixing chamber and nozzle passage.
- the invention is related to a cutting head for a fluid jet cutting machine.
- the cutting head has a longitudinal fluid flow axis, such as a water flow axis, concentric with an orifice in an orifice element and a passage in a nozzle that directs the jet toward a workpiece.
- the cutting head has a body with a longitudinal axis and a relatively large upstream water inlet chamber for receiving water under ultra high pressure.
- An orifice element having a relatively small orifice or hole is aligned with the axis and open to the chamber.
- the orifice element is mounted on a holder having an outlet passage axially aligned with the axis in communication with the orifice.
- the holder has a cone shaped surface which cooperates with a converging cone shaped recess in the body to axially align the orifice with a longitudinal axis of the body.
- the body has a transverse bore accommodating an insert having an abrasive mixing chamber aligned with the longitudinal axis.
- An elongated nozzle having a passage aligned with the longitudinal axis is mounted on the body below the insert.
- a collet grips the nozzle to hold the nozzle on the body.
- the body has an upwardly directed cone shaped surface engagable with tapered surfaces of the collet to align the passage of the nozzle with the longitudinal axis of the body.
- the cone shaped surfaces of the body are precision machined so that they are concentric with each other relative to the longitudinal axis of the body.
- the nozzle is centered relative to its inner diameter to insure concentric alignment of the nozzle passage with the longitudinal axis.
- the orifice element and holder are replaced as a unit from the body.
- the cooperating cone shaped surfaces of the holder and body insure alignment of the orifice with the longitudinal axis of the body.
- the cone shaped surfaces of the collet and body concentrically locate the nozzle passage with the longitudinal axis.
- the alignment of the nozzle with the longitudinal axis results in even and centered wear of the internal passage of the nozzle thereby extending the use of the nozzle.
- the cutting head has a relatively short distance between the orifice and the entrance to the nozzle passage which keeps the water steam coherent and minimizes angular misalignment between the water stream and the nozzle passage.
- the body engages a pilot surface on a coupling which minimizes angular and parallel misalignment.

- Other types of liquids and mixture of liquids can be used in the jet cutting apparatus.
- Water under ultra high pressure such as 25,000 psi or more is generated by an intensifier 14 and delivered to cutting head 13.
- a pump 16 supplies water under pressure via a reversing solenoid valve 17 to operate intensifier 14.
- a water supply 18 under nominal pressure is delivered to intensifier 14 which in turn increases the pressure of the water and discharges the water to lines or tubes 19 and 21 leading to an accumulator 22.
- a conduit pipe or hose 23 delivers water at ultra high pressure water, such as 60,000 or more psi, from accumulator 22 to the inlet of cutting head 13.
- ultra high pressure water such as 60,000 or more psi
- An example of an intensifier for delivering a flow of ultra high pressure water is disclosed in U.S. Patent application Ser. No. 493,422, incorporated herein by reference.
- Cutting head 13 is moved relative to workpiece 11 to cut designated parts from the workpiece.

- Seal 54 is an O-ring located within seal 53.
- Seal 53 is an annular plastic member that functions as a compressed back up element for the O-ring.
- the face seal assembly requires lower sealing torque than static crush seals.
- the face seal assembly permits metal to metal contact between boss 51 and the cylindrical wall 55 surrounding recess 52 to assure consistent nozzle alignment.
- the cylindrical wall 55 is a pilot surface concentric with longitudinal axis 35 to preserve longitudinal alignment of body 37 with coupling 43.
- Body 37 can be removed from coupling 43 and replaced without recalibrating the longitudinal alignment of the body relative to the coupling. This ensures consistent water exit stream location relative to the water motion system.
- body 37 has a cylindrical wall 58 at the base of chamber 38.
